In Figure 1, three ejeetors are shown arranged in series with interlm'diiite rondensersi the third or last ejertor of the series being constructed in areordanco with my inventii' n. and consisting of three discharging units. In Fig. 2, two ejectors are shown in series with intermediate vondensatiop, the second or inst ejeetor (-onsisting of two charging units in sword-(moo with my in .rcntion. Fig. is a. modification of Fig. 2,
